SPECIFICATION forming partof Letters Patent No. 436,849, dated September 23, 1.890. Application filed March 19, 1889. Serial No. 303,927. (No model.) V

T0 all whom t mag/concern:

Be it known that I, ISAAC N. FORBES, a citizen of the United States, residing in the city and State ot' New York, have invented anew and useful Lasting-Machine, of which the fol lowing is a specification.

My invention consists of an Improved machine for lasting bootsl orV shoes, wherebythe entire process of shaping the upper around and to the last and insole when placed in the machine can be performed with great directness, speed, and economy, a distinguishing feature of the vInachine being the simulta-` neous movement, through a single crank or wheel by one hand of the operator, of all the mechanism required in the operation, except- Asists of,iirst, a table of proper s hape, size, and 'elevation for sustaining the machinery, and,

second, a proper gear beneath the table with a vshaft extending to the front, to which a crank or wheel is secured for receiving the power for drivingV all the gear up to and including the forming-clamps at both sides and ends of the last. Part ot this gear consists of four upright levers that extend through slots in the table near. the opposite sides and ends thereof. They have adjustable fulcrums and connect the gear beneath the table with that above. Third, a movable and adjustable head, from which is suspended a collection of pliers for stretching and drawing the upper to the last, and which also carries the mechanism for operating and disengaging thepliers.

The mechanical devices, their form, arrangement, and combinations, by which I attain the objects ot this invention, are illustrated by, the accompanying drawings, in which similar letters and tigures represent similar parts, except those representing sectional lines, which are fully explained.

Description of table.

A, Fig. 1, represents the table, with a plane top surface, in which is a T-groove A', eX- tending centrally from end to end. It has a proper thickness of metal beneath for equal strength and a recess (115 (see Plates 3 and 6, Figs. 3, 152, and 154) cut out equal to the outside of the bottom part of the T-slot A' in width, and in length equal to the lengt-h of the bolt-head m' and the head of stand-shaft M3.

Around the entire outer surface of the table is the flange awith an extension a3 at each end, upon which the sheet-metal legs A2 aresecured by rivets or bolts, as required. Cross-connecting ribs a' and a2 are cast for strength to the table, and bushed bearings C017 @1711 are fitted, and in which the slide-screw shafts L L fit and work, and at opposite sides in the middle of the table beneath are cast guides a4 i411 dressed out with grooves a5 (see Fig. 15') in each side, in which tongued slide-bearing pieces b fit. (See Plate 6, Figs. 21 to 213, inclusive.) Guides a4 (see Plate 6, Figs. 15, 15', 152, and 155) extend straight their full length on the bottom, while their mates a4# are cut J. from the bottom up and from theirinner ends to their bosses a5, (see Figs. 15, 15', and 152,) allowing space for connecting-levers C and Fig. 49 is an inner side View of rods d to work. =The extensions at? ofv the upper portion of the castings of these guides connect to the center hub a9, (see -Plate 6, Figs. 152 and 155,) thus adding support to their several parts. Upon the outer sides of the cast-guides a4 651i* are bosses a5, which form supports to the guides a4 and c0111', and are provided with threaded holes in which threaded bolts it for securing bearing-plate A8 (see Plate 6, Figs. 16 and 16') in position by bolts. (See Plates 3 and 4, Figs. 3, 9, and 10.)

At the opposite sides in the middle of the table are slots a7, (see Plates 4 and 6, Figs. 9, 152, and 154,) through which the side-arm-connecting levers B B pass for connecting the lower with the upper side gear. Between ribs a' and a2 slots a5 (see Plates 3 and 6,Figs. 3, 15', and 155) are cut through the table for the entire distance, and in width-equal to the top portion of the T-slot A', through which the end shifting connecting-levers H H pass and work, connecting theV lower andupper end gear together.

In the center of the table is a hub a9, (see Figs. 152 and 155,) having a bearing-bushing c6111, (see Plate 6, Figs. 232 and 233,) in which the upper end of the three-flanged center shaft D fits. (See Plates 3 and 4, Figs. 3 and 9.) Near the hub is recessed guide (r11, (see Plates 3 and 6, Figs. 3, 15', 153, and 155,) dressed out, forming a guide for the nut E', in which it fits for working to and fro upon its shaft. Short ribs @12 and @13 connect crossrib a2 to the backs of bosses a5 (see Plates 3 and 6, Figs. 3, 15, 15', and 153) with a bearinghole through rib @12 and in rib @13. A hole through the front ange a of the table is recessed, in which a sleeve-bearing E2 fits and is secured in position by nut E3. (See Plate 6, Fig. 15, in position, and Figs. 20' and 203, disconnected and shown in two views.) The main screw-shaft E, which is operated by the front crank E7, fits and works at its front end in this sleeve-bearing E2, having its other end in sleeve-bearing E5, that is driven in the boss of the rib C013. (See Figs. 15, 153, and 155.) In the back end of sleeve-bearing E5 stopbearing E6 lits against the end of shaft E and is pressed by setscrew a11, that passes through ange a and its connections for taking up slack motion. (See Plate 6, Figs. 15 and 155.)

Holes are bored in line from end to end of table through flanges d, a', and a2. The holes in a' and d2 are of different sizes to accommodate the different sizes of bearing-bushes required for the two portions of the end slide-screw shafts L L that [it and work in them. (See Plates 3 and 6, Figs. 3 and 15, in position and detached in Figs. 25 and 25'.) In the crossconnecting ribs a2 are bosses c', in which holes are bored and threaded for receiving the hinge screw-bolt,` by which the outer ends of connecting-rods C C are secured. Projections e391, extending below from the main plate of the table, and e3 from the rib L13 above setscrew connection, are similar points of connectio'" (see Plate 6, Figs. 15, 15', and 153) IOO IIO

where the ends of connecting-rods e are hinged by screw-bolts, which pass through the ends of the rods and screw in their respective bear ings.

A2 represents the table-legs, (see Plate 1, Figs. 1, 1, and 13, also broken connections to table on Plate 3, Figs. 3 and 5,) constructed mainly of sheet metal iitted to frames, with T or L. frames A6 inside at proper distances apart, riveted or otherwise secured thereto for drawers to suit, which tit between. The upper parts of the legs are fitted to the flanges a3 a3, which are extensions of the anges a a, at each end of the table, and to extensions of ribs a across the table (see Plates 1 and 6, Figs. 1, 1', 13, and 15 to 153, inclusive) and riveted to their bases A3. (See Plates 1 and 2, Figs. l and 1'.)

A7 are the bottoms, on which the drawers rest.

A4 are spaces in the legs for drawers.

A5 is a drawer constructed of sheet metal, secured to the cast-metal end. Lock-drawers are placed in the legs under both ends of the table and extend across it. The space can thus be utilized as a receptacle for such tools, appliances, and duplicate parts of the machine, dac., as maybe required, and if more room is needed the entire remaining space beneath the table can be shelved for the purpose.

Gear beneath the table.

On Plate 6, Fig. 20, E represents a screwshaft.

E is a toothed slide-nut on shaft E, and Figs. 22 and 22 (two views) show nut E in gear with the toothed wheel D.

E3 (see Figs. 20 and 203) is a flanged bearing-sleeve for crank-shaft E, which passes through ange a' and rib @13. (See Fig. 15.) E3 is a nut which secures said bearing-sleeve in position.

E3 is a stop-collar on shaft E for limiting the travel in its guide a of slide-nut F. on crank-shaft to prevent damage when tightening the end and side clamps around the upper on the last, and is also a guide for adj ustments of side and end clamps. These adj ustments should be made when the nut E is back against the stop-collar El, and the side and end clamps are closed around the last. They are made by means of the side and end adjustable screw-fulcrums of levers B B and H H, respectively, and the possibility of injury to either last or upper that otherwise might occur is thus prevented.

D, Figs. 23 and 23', is a three-hanged vertical center shaft (shown also on Plates 3 and 4, Figs. 3 and 9, in position) secured by pins to the tooth gear-wheel D.

In Figs. 233 and 233, am is bearing-bushing, in, which the upper end of shaft D works and which is driven in hub a3 for purpose of renewal when required. It is shown in position on Plates 3 and 4, Figs. 3 and 9, with bearing-plate A3, Figs. 16 16', which latter forms alower bearing afor the three-iianged center shaft, and is secured to bosses a3, as before stated. (See it in position in Figs. 3, 9, and 10, Plates 3 and 4.)

b, Figs. 21, 21', 213, and 213, are tongued and mortised slide-bearing guide-pieces, which iit in grooves 0,3 in guides a4 and at?. They have horizontal mortises b3, in which the cornbined slide and hinge joint, hereinafter de'- scribed, ts and works, and to which the ends of connecting-levers C fit and are secured'. They also contain vertical mortises b. These vertical mortises b in slide-bearing pieces b (see Plates 11, 6, and 7, Figs. 9, 15, 21 to 213, 28, 285, 283, and 287) form the outer bearingsurface in which the combined slide hinge'- joints connecting with the lower ends of armed levers B iit and work. These combined slide hinge-joints also are more fully described hereinafter.

C C, Figs. 26 and 26', are two views of the connecting-lever C, hinged to its bearing c4 in rib a3, (see Plates 3 and 6, Figs. 3 and 15,) its opposite end forming part of the combined slide hinge-joint, which fits and works in. mortise b3 of slide-bearing pieces h, previously described. (lee Figs. 26, 26', 263, 263, and 264, Plate 6.)

d (see Figs. 24 and 24', isolated and in position, Fig. 15) are connecting-rods, whiclrconneet at c3 with rod C (see Figs. 26, 26", 263, and 264) and at their other ends to opposite sides and between the two lower ianges of the three-langed centerl shaft D (see Plates3 and 6, Figs. 3 and 15) and are secured by hingepins which pass through the ends of rods d and the two lower flanges between which they fit. (See Plates 3, 4, and 6, Figs. 3, 9, and 15.) i

e e are conuectingflevers. (See Plate 6, Figs. 27 and 27', disconnected, and connected in Fig. 15.) They have mortises e3 at one end, in which small slide-bearing blocks e fit, having holes through which connecting hingepins e3 pass for connecting with ends of slidescrew shafts L L. (See said shafts on Plate 6, Figs. 25 and 25', disconnected, and connected on Plates 3 and 6, Figs. 3 and 15.) The opposite ends of connecting-levers e e are hinged by threaded bolts, which screw in their bearings @33 @33. (See Figs. 15, 15, and 153.) Rods d d are connected (in the same manner as CZ CZ to connecting-rods e) by hinge-pins to levers c e at e4 eAL by pins e5, (see Figs. 15, 27, and 27,) and at their opposite ends are connected between the two upper flanges of shaft D at ninety degrees (90) from the connections of rods CZ CZ, above mentioned, so that rods d d and rods d d will not only be upon different planes, but upon opposite quarters, and hence will not interfere with the working of each other. These rods d d are hinged by hinge-pins which pass through the ends of the connecting-rods and the two upper flanges of shaft D, and also through the toothedgearwheel D', thus securing it in proper position relative to the hinge-pins, thereby connecting IOO parts L L bb not only with the toothed geari wheel, but also with the toothed rack on the flanged slide-nut, which, with its shaft, must work in `harmony of movement with all the other parts.

L L (see Plates 3 and 6, Figs. 3, 15, 25, and 25) are screw-slide connecting-shafts, which fit in bearing-bushings 6017001751, driven in holes through cross-ribs a' and a2 in the lower part of the table, where they are placedcentrally with it parallel to its upper surface and in line under the T-groove A'. Their centers should be placed the" same distance from the top of the table as the center of the space between the two upper fianges of flange-shaft D, in which the ends of connecting-rods cZ' CZ' ht, (see Plates 3, 4, and 6, Figs. 3, 9, and 15,) and on the. same plane with connecting-levers ce. Hence care should be taken in placing the hinge-bearings est @2t that they also are the proper distance down from the top of the table-viz., equal to the distance of the center ofthe screw-slide shafts L L less one-half the thickness of the connecting-lever E. The centers of the horizontal lnortises h2 b2 in bearing-pieces b b should be the same distance down from the top ofthe table as the distance to the center of the space between the two lower flanges of the three-flanged center shaft D to bring them on the same plane with each other and their connecting-rods CZ CZ and levers O C. and 15.) Hence the hinge-bearings o4 c4, upon which the ends of connecting-levers C C are hinged, should be upon the same plane less one-half the thickness of the lever, and care should also be taken to bring the pressure upon the same line as nearly as possible as the hinge-pins of thelevers C Gand the points ,of engagement of side levers B B in slide-bearings b b. (See Plates 4 and 6, Figs. 9 and 15.)

Shafts L L are provided with adjustable screw-guide bearings composed of three separat-e pieces. The outside guide L' is recessed upon opposite sides to fit slide-bearing pieces h h,whicht and are carried by the hinge-bearing bolts h' in the opposite arms of shifting lever H. (See Plate 6, Figs. 15, 17,17', 172, 18, 18', 182, 19, and 192.) The guide L' is also bored through and the hole recessed upon opposite ends to fit the flanged toothed sleeve-nut Z, which fits the screw upon the shaft L inside and fits the hole in the guide outside. Said sleeve-nut is provided with a separate end flange, and when put together and the end flange riveted fast the sleeve-nut Zis left free to turn upon the screw-shaft L, thus providing for end adjustments by screwing the adjustable screw-guide bearings L' L to and fro on the screw-slide shafts L L to suit all yeXtreme variations requiring accommodation in the various lengths of lasts. The solid fiange on sleeve-nut Z is toothed for turning it by application of a handle toothed rod Z2, (see Plate 6, Figs. 193 and 194,) racked to fit it and by which it can be pushed or pulled, as re- (See Plates 3, 4, and G, Figs. 3, 9,

quired, quicker than can be done bythe fingers direct; or, if the latter is preferred, the toothing of the fiange may be dispensed with and a surface, milled or otherwise, as desired, be substituted. It preferred, the flanged nut Z may be dispensed with and the sleeve-bearing L' may be made to fit the outer surface of the screw-shaft L and separate nuts placed on shaft L at opposite ends of L for end adjustment, instead of the flange-nut Z.

7a h (see Figs. 17, 17', and 172 detached) are slide-guides in which the hinge-bolt pins h Zt' of the shifting-lever H H lit. (See plates 3 and 6, Figs. 3 and 15, connected.)

E7 is the main crank, and drives all gear in the table. It is bent out to pass the projecting end of the adjustable screw-fulcrum, is provided with a handle and a tapered hole to fit the tapered end of crank-shaft E, and is secured in position by a nut on end ofthe shaft. (See plate 6, Figs. 15 and 20.)

a (see Figs. 15 and 156) is a set-screw extending from the back of the table through the fiange a and its connections to the short rib cl2 against the stop end bearing Ein the stop fianged sleeve-bearing E5, that is driven in the boss on rib als and in which the back end of crank screw-shaft E fits. This setscrew a is designed to take up the lost motion in crank-shaft by pressing against the stop E, the other end of the crank-shaft being held firm endwise by stop-collar E4t on the shaft against which the end ot' the sleeve E2 must be brought by the nut E3, thus preventing the possibility of lost end motion inscrew crank-shaft E. n

E5 (see Figs. 15 and 156) is the stop flanged sleeve-bearing for the back end of the crank screw-shaft E. It is driven tight in its bearing in the boss of rib am, and the front or flanged lOO end is the stop which limits the nut E in its travel on the crank-shaft. Hence the opening of the heel and toe or end clamps and the side clamps (see Plates 5 and 6, Figs. 11, 15, and 156) around the last are governed in their movements by the limitationl of the travel of the flanged nut E upon the crank-shaft E at that end in opening the clamps.

b2 b3 (see them on Plates 4 and 7, Figs. 9 and 28, connected, and on Plate 7, Figs. 285, 286, and 287, disconnect-ed) are hinge slidebearings which fit the lower ends of armed levers B B, and which form part of the combined slide-hinge joint that is fully described hereinafter.

Connection of upper and lower gear.

`B B (see Plates 1, 2, 3, 4, 5, and 7, Figs. 1, 2, 3, 9, 10, 11, and 28) are side armed levers for connecting the lower actuating mechanism with the upper side clamp-gear, the lower ends of which levers pass down through crossslots of a7 on opposite sides of the table A, (see Plates 4 and 6, Figs. 9, 152 154,) the ends IIO being rounded to tit the counter-bores of the side pieces Vb2 ofV the hinge slide-joint, (sce at a proper distance above sufficient for clearance the levers are divided into two arms of equal lengths straight and curved to suit the spaces and connections required. They are connected at their upper ends by short connecting-rods b5 b5 to slide-bearing guides 0 and o. (See Plate 7, Figs. 28, 2S', and 282.)

H H .(see Plates 3 and 6, Figs. 3, 17, 17', and 172) are end levers connecting the lower to the upper end or heel and toe clamp gear. They pass up through the slots as as, (see Plates 3 and 6, Figs. 3, 15, and 154,) and the lower end of each is divided, like a common shifting-lever, in two equal arms, in which hinge screw-bolts h fit, the inner ends of which form hinge-pins for slide-bearings h, which bearings tit in the recesses on opposite sides of the guide-bearings L. (See Plates 3 and 6, Figs. 3, 15, 17, 17', and 172.) These bearings guide and control the lower ends of levers H when power is applied tothe crank and transmitted to them through the shaft E, the shafts L, and their connections.

The end levers H H are hinged centrally by hinge pins or bolts h2 (see Plate 3, Fig. 3) to their adjustable fulcruin-bearin gs. Their upper ends, like the lower ends of armed levers B and the end of connecting-rods C, have the same class of jointed bearings and motions, and being constructed upon a new principle, are therefore original, and I designate these jointed bearings as the combined slidehingejoints. They possess two entirely different and independent motions-a hinged central and a straight slide-each ample, simple, and serviceable, qualities essential and desirable, and will be inade the subject of a special patent hereafter. They are constructed as follows: First, the end of each lever or shaft H must be rounded to suit with a hole in the center thereof 3 second, the hinged slide-bearing pieces H3, which are composed of two pieces of equal size and thickness corresponding with the mortise-bearing f, in which they t, are bored through their centers and counterbored to fit the rounded end of lever H in depth equal-to half the thickness of the lever, and also recessed to the same depth from the counterbqre to their surfaces in shape corresponding with the required movement of the lever or shaft H when working in it; third, a hinge-pin H4, which passes through and fits the hole in end of lever H and bearing-pieces H3 flush with their surfaces; fourth, a mortise f, in which the outer surface of the slide-hinge bearing-pieces fit.

For illustration of the combined slide-hinge j oint,`as far as described and illustrated here, see Plates 4, 6, 7, and 9, Figs. 26, 26', 262, 262, 264, 28, 285, 286, 287, 44, 44', 46, and 46.

Description of gear above the table.

H H are adjustable fulcruin-bearing shafts (see Plates 1 and 3, Figs. 1 and 3) for adjusting end clamp-shafts F5 F6 to correspond with the different lengths of lasts. are recessed out, thus leaving a jaw upon each with a hole bored through for pin. Between these jaws lever H tits with a corresponding hole, through which a hin ge-pin h2 fit-s in both, thus hinging the end levers H H to their respective adjustablefulcruin-bearings. These adjustable fulcruni-sh afts H H ypass through their respective stands F F0, the outer endsbeing turned smaller to tit in adjustable flanged screw-sleeves H2 H2 with screw-iiiits h4 h4 upon their ends. The screw-sleeves H2 are slightly recessed on their outer ends to receive a corresponding projection on the inner face of nuts h4 made to lit them, thus forming a stop with a shoulder at the outer ends of the smaller portion of shafts H H', between which and the inner shoulder the screw-sleeves H2 H2 it and work, and by means of the milled iange on their proj ecting ends the sleeves H2 H2 are turned in threaded bushings h3 h2 for adjustment of the shafts H H and the fulcruin-pins h2 carried thereby,by which means speedy and accurate adjustments are obtained of the heel and toe clamps to the lasts in position. The

Their inner ends bushings h2 h2 are of malleable metal, which is essential for a durable thread continually in use, and are screwed into the stands F F0.

f f4 are bolts with long T-heads. They t the T-slot A in the table and the holes in the bottom of the respective stands F F0 for bolting them firmly to the table. (See plates 1 and 3, Figs. 1, 3, and By loosening the nuts on the bolts the stands F F0 are adjustable, if required.

M is an adjustable screw-flan ged stand-tube with a tapered stein upon the top, which enters the holes in the heels of the lasts that rest upon its shoulder, the screw fitting the screw-stand shaft M. For descriptive illustrations of M M and m m m2 m3 (see Plate 8, Figs. 3, 3', 8, 8', and S2.) The lower end of screw-stand shaft M is grooved each side, leaving a T-shaped end which tits the cross T-shaped groove in the adj iistable plate m.

fm is a T-headed bolt which iits T-slot A in the table, passes through adjustable standplate fm, and holds it iirinly by the handlenut m2.

m2 is a set-screw with a pin for a handle that holds the stand-shaft M in position laterally.

Sleeve M is adjustable vertically to suit the required height for lasts, the flange below being milled for convenience in screwing up or down, and its stand is also adjustable both transversely and longitudinally at will to suit the various requirements of lasts.

M2 (for descriptive illustrations of M2, M3, M4, m3, m4, m5, m6, m7, and m2, see Plates 3 and 5, Figs. 8, 14, 14, and 142) is an adjustable stand-screw tube for supporting the toe of the last. It has a stem upon the top which IOO IIO

iits in the toe-rest M4. It also fits the screw ot the adjustable screw-stand shaft M3, and is adjustable vertically to suit the required height of lasts by screwing the tube M2 up or down on the shaft M3 to suit, and shaft M3 is adjustable in T-groove A in the top of the table to suit the different lengths ot lasts.

m4 is a tongued washer which tits the upper portion ot groove A in table. It also fits the stand-shaft M3, which passes through the hole in the center.

m5 isa nut with a handle for screwing,r the stand-shaft M3 firmly to the table. (See Plates 3 and 5, Figs. 3, 14, 14', and 143.)

M4 is an adjustable toe-rest to accommodate the width near the toe of the various sizes of lasts. It has a hole in its base for a The upper portion is grooved out from the top down, or laterally mortised, in which the horizontal bars m m3 lit, side by side, and are adjustable, and from the top ot' these bars up the groove is increased a little inside, thus leaving a small shoulder upon opposite sides, in which a piece m iits, filling the space in the groove from the shouldersup, and upon opposite sides outside even with the shoulders are recesses in which side clamps m7 m7 fit. (See Figs. 14, 14', and 142.) These side clamps curve in a little at the top for holding rubber m3, which forms an elastic rest for toe of the last. These clamps, the two sides, and the 'piece between are all riveted iirmly together 'by rlvets m10, leaving a mortise in which the adjustable bars m3 m ot side guides iit.

m3 m6 are adjustable side guides to fit the opposite sides of lasts near their-'toes and direct them centrally to the toe-clamp.

m3 is a piece ot rubber or other yielding substance secured by clamps miin the top of toe-rest, which yields to the pressure upon the last from the last-fastener and prevents damage to the upper.

I (see Plates 2 and 4, Figs. 2, 9,and10,in position, and 93, 96, and 97,detached) are side dan ged adjustable fulcrum screw-sleeves which screw in stands i3. They are bored to tit the shafts I' I and recessed in the ends to tit the nuts t", that are screwed on the ends of the shafts upon which the sleeves have a working iit in the space between the shoulder and the nut. The fianges of sleeves I are milled for convenience of screwing in or out, and it is by their movement that adjustment ot' the side clamps is made to tit different lasts.

I' I' (see Plate 4, Figs. 9, 93, 94, and 10) are the adjustable slide-pieces of the fulcrums with jaws, between which levers B B it, and to which they are hinged by the pins e'.

i2 are adjustable fulcrum screw-stands (see Plate 4, Figs. 9 and 10, in position, and 93, 93, and 940, detached,) which are secured by bolts to the table at its opposite sides, and in which adjustable bearings l fit, and are screwed for adjusting side clamps G G' G2 G3, (see Plates 4 and 5, Figs. 9, 10, and 11,) through adjustwhich speedy andl accurate end adjustments of the heel and toe or end clamps to the last are attained when set in harmony with their gear-connections. These stands are dressed on their bottoms with small tongue or guide pins to fit the top ot' groove A in table, having bolt-holes in which bolts f3 iit. The heads of these bolts, fitting in the T-shaped slot A' in top of table, pass up through the bases of the stands, and with nuts screwed on top, hold the stands F and F0 firmly in position, while they are also adjustable on the table, if required, in cases ot extreme difterence in length of lasts. Ordinary differences can always be accommodated by means ot the adjustable fulerums H' H. The inner portions ot the stands at each side of the nut are recessed to make room for the wrench in turning the nut. The upright portions of the fram es are each T-shaped in cross-sec tion with suitable projections or bosses, in which the adjustable screw-fulcru m, sleeves, and shafts iit. The upper ends of the stands are of suitable form for clamps, and bored out to receive the sleeves F3 F4. The clamp-heads F' and F2 are split open lengthwise with a boss on each side, through which the screw-bolt f3 passes. The screw-bolt has a bent handle f3 on one end, the oppositeend being threaded in the boss, which permits of tightening or loosening at will, for adjustment of the sleeves F3 and F4, that can thus be securely clamped and held in any required position. To avoid danger of bending the clamps by too heavy pressure, a plate f7 is inserted in the open cut in each of the clamp-heads F' F2, through which the clamp-bolt passes. (See Plates 3 and 5, Figs. 5, 5', 52, and 11.) i

' The adjustable connecting-sleeves F3 at the toe and F4 at the heel (see Plates 3, 5, and 9, Figs. 3, 1l, 44, 44', 47, and 47') have near their front ends projections f1 f, Figs. 47 and 47', with a threaded hole through each in which arms 7445 are screwed in opposite Sides solid up to their collars with balls fw on their outer ends, which tit in the side socketjoints of the outer endsot' connecting-rods )413 and the holes therein. (See, also, Figs. 49 to 493, inclusive.) The projectionflo, Fig. 47, on sleeve F3 for the toe attachments is made deeper than the projection f u, Fig. 47', on sleeve F4 for the heel, in order to place balls f 13 f16 upon the respective arms f3 and f4 of the clamps on a line as near as possible with the average angle required of the respective heel and toe clamps to iit the different lasts, and that the rods f, which connect balls f14 and f16 together, shall correspond in average inclination with their respective heel and toe clamps.

Holes are bored through opposite sides of the sleeves F3 and F4, in which guide-pins]p17 IOO IIO

l toe and heel shafts F and F3, in which they lit and keep the sleeves from turning, or, if preferred, guide-pins may be driven through opposite sides of the clamp-heads F and F2 and corresponding grooves made in the outside of the sleeves F3 F4 for the pins to work in instead of grooves in the sides of the clampshafts F3 F3'.

The adjustable slide end (or toe and heel) clamp-shafts F5 and F6 (see Plates 1,3, 5, and

9, Figs. 1, e, 11, 44, 44', 442, 443, 47, and 47').

are of the same construction in every respect, except that one is for thel right or toe and the other for the left or heel end of the machine. They have near their front (inner) ends mortises f, forming the outer bearing, in which the combined slide hinge-joints of the upper ends of end levers H fit and work. They also have curved extensions at their front ends, forming segmental bearings F3, which contain a T-shaped groove f', turned out in the inner part, in which the segmental clamp-bearing pieces F9 lit. About the middle of the curved extension is the hole f1, from which to the end is the clamp fgo, with an open cut separating its two parts. (See Figs. 44 443, and 443.) At their ends are the bosses or ears fm, in which are the clampscrew bolts f22 with handle f23, by which the clamp-bearings of shafts F5 and F6 can be tightened or loosened at will and their segmental counter parts F3, that are clutched by them, canbe adj usted and completely clamped and held in position, as required. These shafts being right and left hand with clampbolts entering from their front sides, the boltholes and screws must be in harmony therewith.

F9 F3 (see Plates 3, 5, and 9, Figs. 3, ll, 44, 44', 443, and 443) are bearing-pieces which form the segment of a circle on the back part, and are shaped as counter parts to fit in the T- shaped recessed circular bearings f', and on their front part have bearingproj ections f 34, (see Figs. 44, 44', 443, 45, 45, 453, and 453, Plate 9,) in which the side pieces of end clamps 5o f3 f4 or f3 f3m lit. with a hole through each,

in which a hinge-pin fg fits, and between which the end clamps f3.74 or f3f43,as may be, fit and work. (See Figs. 44 and 44'.) The hole and pin tting it are made smaller in part of the lower projectionto permit sloping off the heel-clamps at bottom, as shown on Fig. 44', without weakening that part of the bearing-pieces f24.

f3 f4 or f3 f4a are the two mated sides of the end (orgheel and toe) clamps. Vhen placed together, with the hinge-pin f25 through them, they form avariably-curved and continuouslysmooth front face with surface-joint, hinged with a straight central joint, that in whatever position placed when working leaves no opening on face of the clamp to catch and injure the upper, although formed of curves having different radii. (See Plates 3, 5, and 9, Figs. 3, 1l, 44, 44', 443, 443, 444, 443, 443, and 48 to 481,3, inclusive, which fully illustrate them.) One of said clamps or jaws has a reverselycurved surface concentric with the hinge pin or pivot, and the other terminates at its inner end in an edge which is adapted to fit said curved surface in all positions of the jaws.

Fig. 44 is the bottoni view of Fig. 44', turned upside down with a part of the clamp-shaft F5 broken and sectioned, with clamp-bolt f33 removed, and shows also the combined slidehinge bearing; also the bearing piece F3, sectioned on line 3, Figs. 44 and 443; also sleeve F3 for toe-shaft F3, the balance shown full.

Fig. 44 is a side and sectional view of Fig. 44, being centrally sectional all except a part of end slide-clamp shaft F5 and hinge-pin f33, which are full.

Fig. 446 represents the clamp sides f3 f4 as they would be se`en on dotted line, Fig. 44, as shown by arrows, with the balance of the figure removed, and is the toe or right-hand end clamp. l

Fig. 48 represents the two clamp sides f3 f4 of the heel-clamp viewed from the same position as that of Fig. 443, and made the same, except the inner face of thc bottom half of the clamp, which is dressed off more than the toe-clamp, Fig. 443, to conform to the difference in shape between the heel and toe ends of a last.

In Fig. 44 the toe-clamp is shown, and the dotted line represents the shape of the inner face for'a heel-clamp, as in'Fig. 48. y

f3 are the projecting upper portions of the heel and toe clamp mates f3 f'1f33 f, which gather in and press upon the upper over the insole as they approach the last and hold it until secured to the insole. The main front face of each of the mates f3 f4 f3 f4 is equal in depth to the two combined at their hinge. (See illustrations, Plate 9.)

To fully understand Figs. 446 and 48, Plate 9, it must be bornein mind that the two sides f3f'1f3 f4 are together, as shown in Fig. 44, viewed as indicated by arrows on dotted line of that figure turned upside down, with balance of the figure removed.

Figs. 444 and 443 are parts of Fig. 443 shown separately, thepart fl being taken up bodily and set over to the left, and f3 being "simply rolled over, the other side up.

In Figs. 44 and 44 the end clamp-bearing piece F3, hence the clamp f3 f4, is set straight with the end clamp-shaft F3, and not upon the angle at which said piece and jaws would require to be to fit the toe of a last, as shown on Plate 3, Fig. 8, with the end clamp fitting the last and upon a line with the connectingrods fm, which position is readily given to them by slackening the bolt f3? by means of the handle f33, which slackens the' clamp f3@ and permits the adjustment of bearing-piece F9 with its end clamp at any angle to fit the last, whether heel or toe, and when fitted bolt IOO IIO

f22 is at once tightened, which tightens clamp f20 on end clamp-loearingF"J and locks it firmly until readjustment is required.

Figs. 48, 482, 4811, 4812, and 4813 are the two side pieces f3 and f4a of the heel-clamp in different positions. Fig. 48, as above shown, is indicated by arrow on dotted line, Fig. 44, turned right side up with clamp closed, and Fig. 482 is a cross vertical central sectional view of the same shown wide open, though Fig. 44 is toe-clamp; and Figs. 48 and 482 are heel-clamps.

Fig. 48 shows the two side pieces f 3 and f4 of the toe-clamp bottom side up and wide open. Fig. 483 is the same turned right side up. f 3 at the center joint is the lower side piece of the toe-clamp, and f4, its mate, is the upper side piece at the the center joint of the toeclamp. Figs. 481 and 487 show the bottom sides of the respective pieces f3 f4 separated, and Figs. 485 and 483 show the top sides of the same pieces separated. Figs. 483 and 48g are the front face views of the two respective pieces.

Fig. 4810 is the front face view of f3 f4 wide open. Fig. 4811 is the bottom view of Fig. 482,

showing the two side pieces f3 and f4 of the heel-clamps together as they belong, wide open and turned bottom side up, and Figs. 4812 and 4813 show the two separate pieces f3 and f1l turned bottom side up. These heel and toe clamps are what are herein termed end clamps.

Fig. 442 is the front face view of Fig. 44. Upon the opposite ends from the jaws of the two side piecesf3-andf1 and f3a and f8 of the end clamps are arms, curved, as required, to snit each other in opening and closing, and also to suit their respective connecting-rods f12. They have balls f11 on their outer ends, the centers of which are in the plane of the line or joint between the two halves or sides f3 f4 f3 f4LL when mated together. (See Plate 9, Figs. 442, 446, 48, 4810, and 4811.) When placed in position ready for working, said balls f14 occupy one end of their respective connecting-rods f12, the sockets at the other end of the latter being occupied by balls f1 of the arms f15, that are firmly screwed in their bearings near the ends of their respective adjustable sleeves F3 F4. When thus in position, the balls f14 arel on opposite sides of the clamp-hinge pin f25, each ball being the same distance from the clamp-hinge and each clamp-jaw of the same length. Hence each ball remains upon the same plane with its mate in the same clamp and each side works alike.

lrVhen the sleeves F3 and F4 (see Plates l, 8, 5, and 9, Figs. l, 8, ll, 44, 44', and 442) areadj usted, as required, to suit the ends of thelast and the gears of the machine, and are firmly clamped by the clamp-heads F and F2, they hold the balls f16 of socket-joints in the outer ends ot' connecting-rods f12 firmly in place, 'while the inner ends of the rods, being connected by balls f14, are free to respond to the movements of the mechanism below thetable through the connecting-levers H, which, acting through the combined slide-hinge joint at f,the side connecting-ball, and socket-joints in inner ends of rods f12 and their connections with the arms of heel and toe clamps f3f4 and f3 f1, cause the simultaneous and corresponding movement of both clamps at the ends of the last.

On Plates l, 3, 5, and 9, Figs. l, 3, 1l, 44, 44', 442, and 49 to 495, inclusive, are full illustrations of the ball-and-socket jointed side connecting-rods f 12, with their ball-an (3l-socket joints near the ends of each. They furnish complete automatic adjustable joints for ample accommodation to the various lines of motion required.

The inner ends of the socket screw-plugs f13 are dressed with sockets t-o iit the balls, and their corners or edges are beveled. Their shoulders are made concave to inclose the convex ends of connecting-rods into which they are screwed, thereby preventing possibility of the rods opening from their sides. Referring to the description of this ball-andsocket joint with side connections of a connecting rod or shaft, its illustrations in the accompanying drawings, and its obvious utility,and knowing of no prior invention or use of it, I claim it as an original invention of my own, to be hereinafter made the subject of specialapplication for a patent.

G and G', G2 and G3 (see Plates 4, 5, and 7, Figs. 9, l0, 1l, 28, 30, 3l', and 312) are the sideforming clamps for operating directly on the upper and bringing it on and over the sides of the last. They are composed of a series of fingers g, flattened on the front part and rounded into parallel shanks at their other ends to fit the linger-clamps g in vise tubes or frames G4, in which they are held. (See Plate 7, Figs. 3l and 312, where said clamps are shown in broken portions of increased size and in position on Plate 4, Figs. 9 and l0.) The front ends of the lingers are dressed to correspond approximately with the average shape of the side lines of a last, whether for right or left foot or inner or outer side of the last. (See Plate 5, Fig. ll, and Plate 7, Fig. 80.) The outside fingers may be a little wider or narrower than the others on their outer edges, if required, to better iit the spaces between the ondand side clamps forvariousleugths of lasts. For the complete adjustment of these fingers the holes or slots, as may be, in the vise-tubes G4 are sufficiently large to permit them to move laterally and vertically. Each of the clamps that secure them in the tubes is independent of its fellows and movable in its place. The whole, when clamped together as one body, ismovable vertically by revolving the tubes that contain them on their respective cross-head journals, which form a horizontal axis. They are thus made perfectly adjustable in every direction, can be moved either singly or collectively, inward or outward, upward or downward, or turned in their ICO ITS

There are double sets of the side clamps, G2 and G2 being for the right and G and G for the left foot last. (See Plates 5 and 7, Figs. 11 and 30.) The set in use belong in the two upper vise-tubes, and are adjusted to it the two sidesinner and outer-sot the last then in the machine. When the last is changed from `right to left, or vice versa, the change of clamps is made by disconnecting the screw-gear shown in Fig. 32 and throwing it into the position shown in Fig. 32', which is done by throwing the hinged stopstud o9 out of its position in Fig. 32, (see Plate 7,) when the clamps and the clampframes on each side, including .the two visetubes G4 and their cross-heads G5 and G6, can be revolved on'their respective crosshead journals, so as to bring the lower tubes with their clamps into position above for working.

G'l (see Plates 1, 4, 5, and 7, Figs. 1, 9, 10, 11, 28, 30, 31, 31', and 312,) are the vise-clamp tubes or frames in which iinger-clamps g iit. They have iinger-holes g8 orslots, as in modications G7, GS, and G2, (see Figs. 118, 119, and 1110, Plate 5,) through which the shanks of 1ingers g pass to theirbearingsbetween the 1in ger- -clamps g. They are bored out straight their entire length, and have a female screw cut in each end, in which set-screws g2 fit. They are also shouldered on the outside at each end to exact equal length, and turned to iit the holes at each end of the cross-heads G5 and G6. The iinger-holes g8, opposite each otherin the tubes, or the slotted modiiications of them shown in Figs. 112, 119, and 1110,Plate 5, are made slightly larger than the shanks of the fingers and enlarged outwardly to perinit the latter to play freely in all directions when being adjusted, and are placed opposite the centers of their clamps g in the tubes. (See Plate 5, Figs. 28, 31, 31, and 312.

G27, G8, and G9 (Plate 5, Figs. 118, 119, and 1110) are tubes or frames having modifications of the openings in opposite sides of the tubes through which the shanks of fingers are inserted, consisting of slots instead of fingerholes, all other component parts remaining the same. In Fig. 118 the tube has one continuous slot on each side of the tube extending almost the entire distance between the cross-heads. Fig. 119 shows the slot divided into two parts by a junction of the two oppo- Athe uppers on the lasts.

site sides midway of the tube, which is thus stiffened and strengthened. Fig. 1110 shows a division ot the slot into three equal parts by two similar connections, and in this manner any number of connections can be made, as may be deemed advisable for convenience or to add strength to the tube; but whatever number may be used the separations between the slots must be placed centrally between two ngers and occupy vno more space than that between two holes when the latter only are` used, and when slots of considerable Vlength are used instead of holes the tubes should be increased in thickness for sufficient strength.

G5 G5 are the cross-heads belonging to the end of the tubes toward the right-hand end of the machine. (See Plate 7, Figs. 28, 282, 32, 32', 325, and 32.) Gi G6 are those on the lefthand end. (See Plates 5 and 7, Figs. 115, 116, 117, 28, 28', and 30.) In the holes at the end of their respective cross-heads the ends of the vise-tubes G4, or their modifications G7, G8, G2, rit, and are placed by the following method of adjustment: They are iirst placed with their ringer-holes-or slots, as may bein such position relative to a central line drawn longitudinally through the cross-heads as will bring the fingers g on an average line approximatingfto and best suited for making the iinal accurate adjustments required to fit This permits the crossheads to stand at any required angle, whether vertical or inclined. The crossheads are set in the position indicated in the illustrations on Plates 4 and 7, Figs. 9, 10, and 28', for the reasons that while the iingers are nearly horizontal, in which position they are most convenient for accurate adjustment to the last, the cross-heads are set obliqueiy to them, which permits of greater length of ingers, and consequently greater range at their extremities in making -the adjustments for workin the upper tube, and at the same time prevents that greater side extension of fingers when at rest in the lower tube from in- IOO IIO

When the relative position of the finger-holes or slots to the 'cross-heads has been adjusted, as above described, the vise-tubes are placed in the holes in the cross-heads, are driven in, riveted, and pinned fast. (See Figs. 31, 31', and 32, Plate 7.)
